??? Undefined function or variable

I am going mad! I keep getting "??? Undefined function or variable" when I run the function calc_RSI.

I have used "dir" and "path" and the file exists in both?

Case mismatch, perhaps??? ML is case-sensitive in matching variable and
function names.

Well, clearly the function or variable doesn't exist within the scope of the function. But we can't help you beyond repeating the error message back to you if you don't show us some code and tell us why you think the function or variable is defined at the time the code calls for it.

which calc_RSI

Or is it an error in the function? I.e. the function is missing a variable or has a bad function call.

Set a breakpoint right before you call that function. Clear the
command window with the clc command. Then execute the function and
copy the entire contents of the command window and report it back here
in this newsgroup.

It appears I had a file the same name as one of the MATLAB toolboxes and that was wreaking havoc.
